Renderings with Edges Toggle On/Off + Opacity

I render booths. For most booths, it’s not necessary to have the edges visible.

However, as soon as I do something like channeled or diamond-tufted, the rendering no longer works for me as well. I use pictures from the model view instead of the render view.

If I want it to look noticeably obvious that the back is channeled, I have to round the edges, which require me to do some finagling to keep it from rounding edges I don’t want it to.

And for diamond-tufting, I really don’t want to spend so much time rounding everything when it’s more for location than being the most realistic.

Is there a way to toggle it on and off, and maybe control the opacity of the edges?

Id love this too. I like the cartoon look for my steel projects and I think it helps differentiate between parts and helps with comprehension. Love some advice here. I’m hoping the viewer can toggle these on or off…
